Abstract
The impedance mismatch between a rectenna's two components, the antenna and the rectifying diode, represents a serious impediment to improving the rectenna's efficiency. Also, the diode's capacitance and the device equivalent resistance determine the rectenna's cutoff frequency. For the detection of the terahertz-frequency signals, ultrafast rectifying metal-insulator- metal diodes are feasible rectifiers. Here, we investigate the global optimization of the rectenna's efficiency working at 10.6 μm by taking the diode materials' properties into consideration. Our proposed objective function considers the impedance matching between antenna and diode, the device cutoff frequency, and the diode responsivity which governs the rectification efficiency. The optimal parameter set reveals a 5.5% coupling efficiency and a zero-bias responsivity of 6.4 A/W. The desirable material properties and geometry are prescribed. The fabrication of Ti-TiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> /ZnO-Al metal-insulator-insulator-metal diode based on the optimal results is carried out and characterized.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
